Adding Sand

[msjboy]

you can also buy 50 lbs of silica sand I guess which is around $9..... nice white colour almost identical to sand see in tanks; comes it handy for other purposes too. In my area, the brand from Lane Mountain Company is available in different grain sizes... Foundries that do sand casting, and some even glass blowers, sand blastng ( though they now use aluminum oxide) uses this grade which works fine with.
